(Savez inženjera metalurgije Srbije, Beograd, 2002)
In this paper investigation of the influence of the solidification conditions on the interface shape and distribution of solute during the solidification of AI-Cu alloy by vertical Bridgman method were investigated. The ...
Inverse gas chromatography of chromia, Part I: Zero surface coverage / Inverzna gasna hromatografija hromoksida, Deo I - nulta površinska pokrivenost
(Serbian Chemical Society, Belgrade, 2001)
The surface properties of the solid obtained from colloidal chromia were investigated by inverse gas chromatography (IGC), at zero surface coverage conditions. The solid samples I dried at 423 K and II heated at 1073 K in ...
Noble metal binding on macroporous poly(GMA-co-EGDMA) modified with ethylenediamine / Vezivanje plemenitih metala za makroporozni poli(GMA-co-EGDMA)kopolimer modifikovan sa etilendiaminom
(Serbian Chemical Society, Belgrade, 2004)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), p(GME), was synthesized by suspension copolymerization and modified by reaction of the pendant epoxy groups with ethylenediamine. The ...
